The roads, bridges, public drinking and water systems, dams, airports and mass transit systems in the US are in need of massive restoration. This is what the American Society of Civil Engineers (ASCE) said in its 2017 Infrastructure Report Card, an assessment of the nation's infrastructure that comes out every 4 years. The organization evaluated it with an overall grade of D+, the same score as in 2013, pointing out that the country will need to invest $4.59 trillion by 2025 to improve its condition.
